We tried running multiple campaigns using LeadRocks but unfortunately leads have info, sales, help, support email ids. Now they are linked to the various CRMs and it shows as erroneous data of high percentage of opens. Another issue is that when you load 7500 leads and upload it on you email marketing tool, it brings it down to 2000 leads because the common ids like support and info are registered on different employee data. Leaving this review after almost a year of usage and we found it as completely useless. We are now buying the data instead.
